SASH-B ALANCE.

Application filed October 31,1 893. Serial No. 489,613. (No model.)

.To all whom it may concern:

Be it known that I, SANDERS B. SUTTON, of

North Baltimore, in the county of Wood and State of Ohio, have invented a new and Improved Sash-Balance, of which the following is a full, clear, and exact description.

The invention relates to sash balances, in which the cords wind on spring acted spools, and the object of the invention is to improve sash balances of this character by increasing their efficiency and making provision. for the ready repair thereof, when necessary.

The invention is distinguished by a novel manner of arranging and mounting the spools, by novel tension or brake devices for the spool, and by other novel details, all as hereinafter particularly described and defined in the claims.

Reference is to be had to the accompanying.

in which similar figures and letters of referonce indicate corresponding parts in all the views.

Figure 1 is a broken front elevation partly in section, showing my improvement applied to a window frame and sash. Fig. 2 is aplan view. Fig. 3 is partly an end elevation and partly a transverse sectional view. Fig. 4 is abroken end view of the drums and the frame in which the drums are supported; and Fig. 5 is a plan view of the tension or brake device.

In providing a window with my improved balance, two drums A are provided centrally of the window, and arranged in the top of the frame 10, and from each drum the two sash cords B, B, or O, O, extend in reverse directions, and from the top and bottom thereof, to the pulleys D, over which the cords pass, and extend downward through the top of the frame to a connection with a sash 20. Each drum is formed with a central" flange or annular bead a, and end flanges a, forming two divisions of each drum, on which the cords wind. The spindle A, on which the drums are mounted is secured in the standards Ef, E of a supporting frame, of which E isthe flat base and is adapted to be secured to the central removable piece 30, of the top of the window frame, the standards E being removably secured to the base, by screws or otherwise, for permitting access to the spools for repairing the same, or the like. A clock xi- J1- at one end bya removable cap F, secured by screws forthe like, whereby ready access may be had to the spring for repairing or renewing it. Below each spool A, a brake head or tension device G is arranged, its ends being guided in slots e in the standards E, E and the upper surface of the head is provided with blocks 9 of rubber, or leather, adapted to bear against the flanges a, a, of the spools. The head G is supported on a bowed spring H, which bears by its ends against the under side of the head G, and is seated at its center on the upper surface s of the base E of the spool supporting frame and the tendency of the spring is to press the blocks you the head G against the spool. Secured to the head G at the center is a guideI in the form of. abolt which is tapped into a bossg' on the head G, and extends downward through the base E, through the removable piece 30 of the window frame, and through a plate J, secured to the under side of the latter, and the distance between the head t'of the bolt and the cross head G, limits the brake action of the spring H, so that by adjusting the bolt, the friction on the spools may be regulated.

It will be seen that the construction is very fect on the spring will be equal on each side of the sash, thereby giving ita proper balance.

In order to prevent the drums from turning while the attachments are being applied, a pin K is provided in one of the standards, as E, and is adapted to enter an aperture a in the drum so as to lock the latter to the standard, as shown best in Fig. 3.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination with the window frame, having pulleys at the top thereof at each side, a central removable piece fitted on the top of the frame, a frame carried by such removable piece, spring-acted drums mounted in said frame, sash cords reversely wound on said drums and passing to each side of the frame 2. The combination with the spring acted over the pulleys therein and connected with sash cord drums, of a brake head,a spring the sash, a brake head normally bearing normally pressing said head against the drum, I 5

against the drums, a bowed spring bearing by and a guide carried by the head and adjust- 5 its ends against said brake head and norably engaging the same, the guide serving to mally pressing the same against the drums; limit the movement of the head by the spring,

and a regulating bolt engaging at its ElPP? substantially as described.

end with the brake head and passing ree y downward through the removable piece car- SANDERS SUTTON 1o rying the drums, and engaging by its head Witnesses:

with the under side of said removable piece A. F. SWINEHART,
